The Avengers is entertaining, no doubt about it. It excites, booming with its super special effects in 3D, and, above all, it fills the eye for each of the 140 minutes in which Joss Whedon tells the incredible story of how the Avengers faced down the bad guy and restored peace to Earth. Iron Man (Robert Downey Jr.), Hulk (Mark Ruffalo), Captain America (Chris Evans), Thor (Chris Hemsworth), the Black Widow (Scarlett Johansonn) and Hawkeye (Jeremy Renner) answer the call. Their aliases, in order, are the billionaire industrialist Tony Stark, the nuclear physicist Bruce Banner, the soldier Steven Rogers, Thor - but he is a god, no alias - Natasha Romanoff and Clint Barton.

About the 3D, it’s useful, once in a while, because it makes the rescue of the Earth even more enjoyable and amusing, makes us feel a part of the movie. It even, if we want to exaggerate, makes us feel like one of Marvel superheroes. We can choose which one. Perhaps Iron Man, who responds to a provocation by Capt America, asking what he is without his suit, with his usual crisp tone of superiority, “Uh, a genius, billionaire, playboy, philanthropist", or Captain America himself, a son of the Second World War. A soldier in his soul and heart, he remained frozen for years, while the world he had helped to save went forward.

Perhaps we want to be Hulk, "the other" as Professor Banner calls his alter ego, the hidden evil side that not only the poor Banner, but in the end each of us harbors in our souls, ready to explode in a sea of ??violence. Maybe the Black Widow or Hawkeye, two deadly killers, or Thor, god of Asgard, who returns to Earth to prevent his half-brother Loki (Tom Hiddleston) from subjecting the world of men to his rule, all through, and perhaps because of, the tesseract, a cube of Asgardian origin through which to create a portal that connects the Earth with the rest of the universe. That is why Nick Fury (Samuel Lee Jackson), head of SHIELD, gathers The Avengers: to protect our world in the knowledge that we are not alone.

The threat, therefore, requires the recruitment of superheroes, who come, some tentatively, others vaguely motivated, to the headquarters. This is the initial problem that separates them: they have no real, felt and shared motivation. They are all too occupied with their super powers, their egos and their reasons, to reason in terms of a team. Thus it happens that, instead of uniting against the enemy, they begin to fight each other to prove to each other their value.
